My new 3d-printed model, a mobius strip of Level 1 of Super Mario Bros., from beginning to end (end being the beginning, in an endless loop for poor Mario).

The loop represents every block, turtle, cloud, and power-up in the level (except for when you go underground in the pipes, that's outside of regular space-time).

I used an image of the whole map and used it as a texture for a plane inside Maya. Then I twisted the plane 180 degrees on the long axis, and bent it around its vertical axis by a factor of 3.1416, that made it into a mobius strip. I color-separated the image in Photoshop and made the sky black, the bricks white, and the in-between shapes in shades of gray, and used that to displace the plane geometry. It was a very heavy file because of this, 100Mb for a simple loop, since there are millions of displaced polygons. Then I uploaded my file to Shapeways, and they 3d-printed it in full-color, with a crazy high resolution.
